problems with transparency in windows

[Anonymous]

Hello all,

I found a problem that I can't get around and so I would appreciate your help.

I am making the rendering of an interior space that has a veranda. Between the room and the veranda there's a glass door and a window. In the veranda there are two windows.
When I'm rendering with my camera inside the room towards the veranda only the interior windows (door and window) are transparent and the veranda windows show in grey. If I position my camera in the veranda the windows that are grey in the first scenario are transparent.
Is there any unknown (to me) rule about having more then a layer of glass in a render? Is there any way of going around this problem? Am I doing something wrong?

Well, hope for your answers.

Thanks in advance for your time.

P.
